[HOW-TO] Apache Reverse Proxy

[welbert]

I am not able to configure the apache reverse proxy, how can I configure it for Notica?

You have to make sure the websocket is being sent through the reverse proxy. Try something like this:

<VirtualHost *:443>                                                                                                     
    ServerName notica.us                                                                                                

    RewriteEngine On                                                                                                    
    RewriteCond %{REQUEST_URI}  ^/sockjs-node          [NC]                                                             
    RewriteRule /(.*)           ws://localhost:3000/$1 [P,L]                                                            

    RewriteEngine On                                                                                                    
    RewriteCond %{REQUEST_URI}  ^/socket.io            [NC]                                                             
    RewriteCond %{QUERY_STRING} transport=websocket    [NC]                                                             
    RewriteRule /(.*)           ws://127.0.0.1:3000/$1 [P,L]                                                            

    RewriteEngine On                                                                                                    
    RewriteCond %{REQUEST_URI}  ^/socket.io            [NC]

    ProxyPass / http://localhost:3000/                                                                                  
    ProxyPassReverse / http://localhost:3000/

    ErrorLog ${APACHE_LOG_DIR}/error.log

Replace notica.us with your domain name, and port 3000 with the one Notica is running on.

I'm tried configure to a other path, like 'domain/notification' I change path "/" of proxy to "/notification", cuz a i have others apps, but i got a blank screen,.

   ProxyPass /notification http://localhost:3000/                                                                                  
   ProxyPassReverse /notification http://localhost:3000/

After search some hours, i change apache conf to

    RewriteEngine On 
    RewriteCond %{HTTP_REFERER} ^https?://[^/]+/notification
    RewriteCond %{REQUEST_URI} !^/notification
    RewriteCond %{THE_REQUEST} ^GET
    RewriteRule ^/(.*) /notification/$1 [QSA,R]
    ProxyPass /notification http://localhost:8086/                                                                                  
    ProxyPassReverse /notification http://localhost:8086/                                                                           
    ProxyPreserveHost On  

but got Unable to connect to the Notica server. Attempting to reconnect...

Any idea?
